Chapter 3 covers the theoretical and computational details for DP Flow.

Its purpose is two-fold:

  • Introduce industry users to some of the general aspects of fluid flow and specifically DP Flow technologies
  • Explain the underlying assumptions and approaches behind the engineering of Rosemount DP Flow products.

Note that an in-depth understanding of the physical relationships that affect DP Flow are useful in helping technical personnel cover all the aspects in the engineering of a specific application, but is not required for the installation and daily operation of DP flowmeters.

What is important to understand is that there is a great deal of complexity that exists under the surface of even the simplest application.
